Abstract : A basic Prisoner's Dilemma matrix was multiplied by one cent, five cents, ten cents, or one hundred cents so as to alter the payoff magnitudes without affecting any of the ratios of values within the matrix. In addition to varying the amount of money at stake, we studied the effect of 'imaginary' versus 'real' money by comparing the situation in which real dollars were used with one in which 'imaginary dollars' were employed. The results indicate that the subjects were more rather than less competitive when playing for 'real' rather than 'imaginary' dollars. No significant differences were obtained among the four real money conditions. These results question the assumption made by some investigators that it is the 'weak incentives' employed in experimental games which lead to the relatively high degree of competition. (Author)
